Use the method of Undetermined Coefficients to find the solution
of the initial value value problem:
y'' + 8y' + 20y = 9cos(2t) - 18e-4t, y(0) = 5. y'(0)
= 0
Solve boundary value problem, use the method of undetermined
coefficients when you solve for the particular solution
y'' + 2y' + y = e-x(cosx-7sinx)
y(0)=0
y(pi) = epi
Use the method of Undetermined Coefficients to find a general
solution of this system X=(x,y)^T
Show the details of your work:
x' = 6 y + 9 t
y' = -6 x + 5
Note answer is: x=A cos 4t + B sin 4t +75/36; y=B cos
6t - A sin 6t -15/6 t
Solve the given Boundary Value Problem. Apply the method
undetermined coefficients when you solve for the particular
solution.
y′′+2y′+y=(e^-x)(cosx−sinx)
y(0)=0,y(π)=e^π
Use method of undetermined coefficients to find a particular
solution of the differential equation ?′′ + 9? = cos3? + 2. Check
that the obtained particular solution satisfies the differential
equation.
